Anxious to facilitate the progress of her pupils, Mary spared no pains to make perspicuous what to them appeared obscure.

The little savages could not, or would net understand that the earth was like a ball, and not only turned upon its own axis, but made the entire circumference of the sun.

A pair of globes could not be procured, and she taxed her ingenuity for a substitute.

Selecting two apples, one enormous, the other medium size, she carefully introduced a reed through the center of the smaller apple, thus causing it to revolve on its axis.

Calling up the tyros in geography, she took the smallest, or "Earth," as she designated it, and while causing it to perform the diurnal motion, she carried it slowly round the larger, or "Sun," as she termed it; thus illustrating the combined movements of our globe.
